Okay i have a pretty mild build here. Its a b20V stroked to 2.2 with p&P head with s2 stage 2 cams. The block has eagle rods and cp piston with 11:5:1 cr. Recently got it running and it bogs really bad, i thought it was my exhaust being too small (2.25 or 2.5 i believe) but that cant be casuing it to bog this bad. I also am getting horrible gas mileage. It is on e85 also with 750cc injectors and yes i know e85 burns alot quicker but it burns way too quick and is giving me horrible gas mileage. The distributer looks like it is advance all the way, could this explain the horrible bog? and yes the ecu is chipped and tune to run e85. Any help would be great and please be nice, i just started interest in all motor and know little bout them.

 

When you say the distributor looks like it's advanced all the way, that gives me the impression that you haven't set the ignition timing.

 

Chipped and tuned? $10 says it wasn't tuned on a dyno. What are your AFR's? What is your base timing set to?

 

how was this stroke to 2.2lt? What size crank and bore do you have?

 

Tune, you need to get it tuned. I had the same problem

 

The previous owner had it tune and dyno so the ecu is tune the old set up. All i did was changed to a hytech header. It is stroked to 2.2 via golden eagle 95mm crank 84mm bore. I didn't think i need to set the ignition timing due because this isn't a new build up, the old owner of the motor had it advance all the way. Would i need to adjust the ignition timing for my set up? If so, what degree? I didn't check base timing but i know the distributor is advance all the way for a lower idle from what the previous owner told me. BTW i'm getting horrible gas milage, mayb 10 miles to a gallon.

 

Forget what the previous owner did, take it to someone who can retune it and is familiar with tuning a car that uses e85.

 

I'm going in for a retune soon but i'm just curious if that bogging and bad gas mileage is due to some other factor other than that it needs a new tune.

 

The internet is not the best place to diagnose engine performance problems.

Maybe your cat is clogged. Maybe your header is banged up so bad that it has become a restriction. Maybe your engine is toast and you are running on only two or three cylinders. Maybe you have a leaking fuel injector. Maybe your MAP sensor is loose and leaking vacuum causing your ECU to be running in column ten when it should be running in column three.Maybe your MAP and TPS sensor connectors are switched. Maybe a plug wire came off. Maybe a spark plug is fouled. Maybe your spark plugs are worn out. Maybe your timing belt jumped a tooth. Maybe you have an electrical problem. Maybe you should have the car tuned by a professional...

 

I could'nt have said that better, props
